House edge is 100 minus the average reported RTP, so the cost column is what the maths implies you pay per $100 staked over the long run. It is not a session prediction, and it excludes any rakeback the casino returns.
House edge is 100 minus the average reported RTP across the games we have on file for each operator. Read the game count alongside it: an average drawn from three hundred titles is steadier than one drawn from thirty.
Why the gaps are so narrow
The whole field sits within a few tenths of a percentage point, because studios build to a band operators will accept. Picking a casino on average RTP alone is therefore close to pointless, and any site presenting that ranking as a dramatic difference is overselling it.
What actually moves your cost of play is elsewhere: whether the operator returns part of its edge to you on every bet, whether that return is locked behind a playthrough, and which build of a given game it chose to run. The last of those is covered in same game, different RTP, where the gaps reach two percentage points, far more than anything in the table above.
